A square poster has a side length of 26 in. Drawn on the poster are four identical triangles. Each triangle has a base of 8 in.
and a height of 8 in. Children play a game in which they each wear a blindfold and place a sticker on the poster. Players who place a sticker inside a triangle win a prize.
Assuming that players will always place a sticker on the poster, what is the probability of placing a sticker in a triangle?
Enter your answer, as a decimal rounded to the nearest hundredth, in the box.

Factoring, you have
h(t) = -16(t^2 -2 -8) = -16(t -4)(t +2)
The ball hits the ground when h(t) = 0, so
0 = -16(t -4)(t +2)
t = 4 or -2
The positive solution is the one of interest.
It will take 4 seconds for the ball to hit the ground.
